Machines for lasting boots and shoes are old and very well known. Suchmachines are illustrated in U. S. Letters Patent No. 365,505, dated June28, 1887. Reference may be had to said patent for a detailed descriptionof said machines. These machines as practically operated prior to myinvention have been provided at the toe end of the machine with one setonly of wiper plates. In these machines when, for any reason, adifferent set of toe plates is desired, the toe plates on the machinehave to be removed and other toe plates attached. Certain disadvantageshave always resulted from this construction. Further, in said priormachines the frame of the machine has been substantially horizontal andno means have been provided for tilting the machine to as- ,sist theoperator in the operation of the ma chine.

A'lasting machine constructed in accordance with my invention involves,first, the pivoting of the bed on the framework 'so that said bed andits attached mechanisms may be tilted at an angle to suit the operator;second, the provision of means for adjusting the height of the bed;third, the provision of a pivoted turret or revolving head for the toeend of the machine, constructed to carry two or more sets of toe wipers,so

that a whole case of shoes, rights and lofts,

may be lasted without removing toe wipers, the head or turret beingturned to bring left toe wipers or right toe wipers in position,according as a right or left shoe is to be lasted. While on thedrawings, only two sets of toe wipers are shown on the revolving turret,any number may be employed.

Referring to the drawings which illustrate such portions of a lastingmachine as is nec essary to show my invention, 1 represents one end. ofa suitable standard, the standard at the other end of the machine beinga duplicateof that shown in Fig. 1. The top of each standard 1, isformed with an inwardly projecting flange 2, (Fig. 8), each adapted toreceive a bolt 3.

l represents a nut arranged on the bolt 3, below the flange 2.

5 represents a nut arranged on the bolt 3 above the flange 2. By meansof the nuts l-, 5, each bolt 3 may be raised or lowered and then clampedin position by turning each nut against the flange 2, the nuts servingto clamp the bolts rigidly to the flange 2. Each of these bolts 3, atits upper end, is formed with a perforated head 6, adapted to receive abolt 7, arranged in a flange 8, at

each side of the bed 9. These bolts 3 support the bed of the machine andenable the operator to adjust said bed to any height that he desires.

10, 11 represent set screws arranged in the bed 9, on either side of thebolts 7, at each end of the machine, and by adjusting these set screws,the bed plate can be tilted to and maintained at any desired angle.

By the above described mechanism, the bed, 9 can be raised or lowered toany desired height, and can also be set at any desired angle at saidheight, and then clamped in that position at said angle and height. Thisenables the operator to adjust the machine so that he can do all hiswork from the heel end of the machine and have free access to the toe onboth sides without requiring the operator to walk around the machine, asin old machines, and enabling the operator to get at both sides of thetoe with equal facility,

.which has not been practical in former machines.

12 represents a treadle pivoted between its ends to the rear side of thestandard 1.

13 represents a rod screw-threaded at each end, the lower end takinginto a screwthreaded socket, pivoted to the rear end of the lever 12.The upper end of the rod 13 takes into a screw-threaded socket 15, theupper end of said socket being pivoted to a plunger 16, arranged in aboX 17 at the rear end of the machine, (Figs. 3 and 5), the said plungerbeing adapted to engage the mechanism supporting the toe wipers to raiseand lower said wipers, as is common in bed lasting machines, andrequires no further description, as it forms no part of my invention.

20, (Fig. 1), represents a jack post, 21 represents a jack spindle, 22represents a last carried by the jack spindle, as is usual. At the rightof the last 22 in Fig. 1, is mechanism which I have designated by thesymbol 23, which embraces means for operating the wiper plates for theheel end of the shoe. This may be of any ordinary or preferredconstruction, as is common, and requires no detailed description as itforms no part of my invention.

Referring to the toe end of the machine, or the lefthand end shown inFig. 1, and to Figs. 1, 3, and 5, the toe piece 13 is shown at the rightside of the figure, supported by a thumb-screw 24, the milled edge ofwhich rests on a support 25, carried by a stem 26, which is adapted tobe engaged by lever mechanism not shown, for raising and lowering thetoe piece 13, as is common, the screw 24 serving to adjust the toe pieceto different sizes of shoes or thicknesses of toes. The upper end of theplunger 16, above the sides of the boX 17 (Fig. 5) is formed with an ear26 on each side. Springs 27 are arranged in oomplemental sockets in thesides of the boX 17, and the cars 26, in order to prevent the shockwhich would take place if the cars 26 directly engaged the top of thebox 17.

30 (Fig. represents a slide arranged on the upper end of the plunger 16,the slide and plunger being formed with a complemental dove-tail membersto permit the slide to move over the end of the plunger and maintainsaid parts together. The upper end of the head of the plunger 16 isformed with a recess 37 (Figs. 3 and 4) in which is arranged a spur gear38. A hand wheel 39 is connected to a short shaft 40, the latter beingarranged in bearings of the walls of the plunger 16, and the spur gear38 being rigidly secured to said shaft.

42 represents a rack secured to the lower side of the slide 30, with itsteeth arranged to be engaged by the teeth of the spur gear 40. Byturning the hand wheel 39, the rack 42 and also the slide 30 can bemoved to the right or left in Fig. 3, or forward and back, in Fig. 5,the head of the milled nut 24 sliding on the support 25 in suchoperation of the machine.

The front end of the slide 30, or the righthand end in Figs. 1 and 3, isformed on either side with an upwardly projecting arm 43. To each ofsaid arms 43 is pivoted an arm 44, connected to and carrying a ring 46(Fig.

47 represents a ring arranged inside the ring 46 and formed at its upperend with a flange 48, resting on top of the ring 46 and preventing thedownward movement: of the ring 47 through the ring 46.

49 represents a plate secured to the under side of the ring 47, the edgeof the plate 49 projecting over and engaging the under side of the ring46. The flange 48 and the ring 49 secure the ring 47 on the ring 46 andprevent movement of one with relation to the other in a verticaldirection, but permits the ring 47 to be turned freely in the ring 46.

The top of the ring 48 is cored out to receive the shank 50 of a spider(see Fig. 4) made up of said shank and two bed plates 51, 52. Thecasting is arranged on top of the shank 50, the said shank 50 with theplate beds 51, 52, being free to turn in the bearing formed by the ring48 and the casting 53, but being restrained by said parts from endwisemovement. The casting 53 by means of the bolts 100 is securely fastenedto the ring 47. The toe wiper bed plates 51, 52, are substantiallyduplicates of each other. Instead of the shank 50 being pron'ded withtwo of such bed plates, it may be provided with any number. As shown,the bed plates 51, 52, are formed with slots 56 adapted to receivecomplen'lental members on the under side of the toe wiper plates, as isusual. Each of said wiper bed plates 51, 52, is equipped with anydesired style or size of tee wiper plates, 54, 55, (see Fig. 3). The

tion 66 adapted to take into a recess 67 (see Fig. 3) corresponding tothe recess 65, but not shown, in Fig. 4, as it is on the lefthand end ofthe shank 50. The projections 64, 66 assist in the free movement of thestud 63, 61 by preventing the tipping or clamping of the studs 61, 63,as they are operated by means hereinafter described. The casting 53 (seeFigs. 3 and 7) is formed with an upwardly projecting flange 68, shapedto form two communicating circular chambers 69, 70, open at the top. Thecasting 53 is also formed with a hollow hub 71, projecting up from themiddle of the chamber 69.

72 represents a spur ear arranged in the chamber 70, (see Fig. 5.

73 represents the upper end of a short shaft upon which is rigidlymounted the spur gear 72. This shaft, midway its ends, is formed with aworm 74, adapted to engage a worm gear 75, secured to the'hub 50 in therecess 76, (Figs. 4 and 5) by means of screws 77. It will be seen thatthe worm gear 75 is secured to the hub on one side of the latter andbetween the ends of the opening 78 in said hub, the Worm gear 7 5 beinga segment and occupyin only a portion of the periphery of the hub 50.

79 represents a flat ring having a milled edge and constituting a handwheel, said ring being arranged on the top of the flange 68. To theinside of said ring, by means of a spline or key 80, is secured a flange81 of a spur gear 82 that meshes with the pinion 72 on the shaft 73.

101 represents a nut engaging screwthreads 102 on the end of the hub 71and clamping on the top of the hand wheel 79 to maintain the latter inposition. By turning the hand wheel 79 the pinion 72 of the shaft 7 3can be rotated, and by means of the worm 74, the segmental worm gear 75,the hub 50 with its bed plates 51, 52, and the plates 54, 55, can beturned on a line running through the chambers 65, 67 as an axis, the hub50 during such motion turning in the bearings formed by the casting 53and the top of the ring 47.

Referring to Figs. 3 and 5, the top of the slide 30, near the inner endof the latter, is formed with a lug 83. 84 represents :1 lug formed withtwo ears 87, 88, that are pivoted by meansof a pin 85 to the lug 83.86represents a rod, the lower end of which by means of nuts 89 and 90,is secured to the lug 84, the nut 90 secured to the lower end of the rodprevents the rod from being pulled out of the lug 84, but permits therod to turn, the nut 89 of the rod and engaging the top of the lug 84prevents the rod from" being pulled down through the lug, but does notinterfere with the turnin of the rod, the nuts 89 and 90 maintaining theend of the rod in position in the lug 84 but permitting the rod to beturned. This rod is arranged in the vertical hole 78 of the hub 50. Theupper end of the rod 86 is formed with a screw-threaded reduced portion92, terminating in a couple of wings 93, 94, projecting from either sideof the re duced screw-threaded portion 92, the lower end of the reducedportion not occupied by said wings constituting a shoulder. representsadisk having a milled edge formed With a circular openin 96 having twolateral recesses 97, 98 (Fig. 6). The opening 96 receives the reducedend 92 of the rod 86, the wing 93 taking into the recess 98, the wing 94taking into the recess 97, the under side of said disk 95 resting on theshoulder of the rod 86. 99 represents a nut arranged on thescrew-threadedportion 92 of the rod 86, adapted to clamp the disk 95against the shoulder. By turning the hand wheel 95 the rod 86 can beturned in either direction. As shown, the rod 86 extends up through thehole 78 of the hub 50 and through the hole 99 of the hub 71 (see Figs. 7and 3). The disk 95 (Fig. 3) is formed on its under side with adownwardly pro- 100 jecting circular flange 100 forming a chamher. 103represents a ring resting on the end of the screw-threaded portion ofthe hub 71, and formed with an upwardly projecting circular flange 104constituting a 105 chamber. 105 represents acoiled spring, arrangedaround the rod 86 and in the chambers formed by the flanges 100,104,thus permitting a certain movement of the rod with relation to the othermechanism, to compensate for changes of angle due to the movement givento the spider, shown in Fig. 4, and the parts carried thereby, whethersaid movement be the turning of the said spider,

or the tipping of the said spider. In the hole 99 (see Figs. 3, 5, and7) is arranged a nut 106 011 the rod 86. 107, 108 represent two screwsarranged in suitable apertures in the hub 71, at opposite sides of thelatter, and adapted to take into the opposite sides of the nut 106 tohold the latter stationary, these screws being connected to the nut 106before the hand wheel 79 and the flange 81 are put in place.

In the described construction, the turning of the hand wheel 95, the nut106 being stationary and rigidly connected to the hub 71, causes theparts supported by the arm 44 (see Fig. 3) to be raised or lowered, the

1 parts moving in the arc of a circle, the center of which is the pivotof the arm &4. This gives in effect a tilting movement to the toewipers.

Referring to Figs. 2, 3, and 5, the ring 46 on the left hand side of themachine (see Fig. 2) is formed with a projecting hub 120 recessed toreceive a pin 36. The ring 47 is formed with recesses 121 correspondingto the number of sets of the wiper plates, to receive the end of the pin36 and thus lock the two rings together, at the proper point to positiona desired set of toe wiper plates in operative position. The pin 36beyond the hub 120 is formed with a reduced portion 122, terminating ina head 35, heretofore referred to. 124: represents a hollow nipple,screwed into the hub 120, the opening in the nipple 124 registering withthe opening in the hub 120. 125 represents a perforated cap arrangedupon the outer end of the nipple 124. As shown, the reduced portion ofthe pin 36 is arranged in the nipple 124. 126 represents a coiled springarranged in the chamber of the nipple 1241 about the reduced portion ofthe pin 36, one end of the spring engaging the cap 125, the other end ofthe spring engaging the shoulder of the hub 120, the spring tending tothrow the pin inward and maintaining the pin in its inner position withthe inner end of the pin of one of the recesses 121. 31 represents abracket secured by a nut 32 to the bed plate 9. This bracket is formedwith an upwardly projecting arm 33. The vertical arm 33 is formed at itsupper end with an inclined or cam member 34, adapted to engage the head35 of a pin 36, for purposes hereinafter described.

lVhen it is desired to use a set of wiper plates not in position forengaging the toe of the last, by depressing the treadle 12 and thuselevating the mechanism controlled by said treadle, the head 35 of thepin 36 is brought into engagement with the incline 3 1 (Fig. 5) whichpulls the pin out of the recess 121, thus unlocking the ring 47 from thering 46 and permitting the rotation of the ring 47 in the ring 16, andthe rotation of the spider about the rod 86 (Fig. 3) until the desiredset of toe pieces has been brought to the front, then by releasing thetreadle, the end of the pin 36 will enter an appropriate recess 121 inthe ring 47 and lock the parts in the new position.

By lasting, as used in this specification and claims, I mean a shapingof the upper about the foot form, and do not include the subsequenttacking or securing of the edges of the shaped upper to the foot form.

In the operation of a machine constructed in accordance with myinvention the jacking and adjusting of the shoe and the manipulation ofthe wipers for drawing the upper about the foot form, both at the heeland toe part, are substantially the same as those that have beenfollowed in prior machines. In my machine, however, the operator isenabled to adjust the mechanism at an incline and also at a heightconvenient for said operator. This presents the foot form and the upperon all sides to the convenient and ready access of the operator. \Vhenfor any reason it is desired to use a different set of toe plate wipersthe treadle is depressed, thereby releasing the look from the ring 17and permitting the revolving of the toe plate mechanism until the properset of toe plates is in operative position. Thereupon the treadle isreleased and the locking pin again locks the rings 4-7 and 16 together.There will be a handle 150 for each set of toe wipers and link and leverconnections, 151, 152, 153, (Fig. 9) between each handle and itscorresponding toe wipers. The operation of the handle and wipers is likethat in the ordinary machine and requires no detailed description.

Having thus explained the nature of my invention and described a way ofconstructing and using the same, though without attempting to set forthall of the forms in which it may be made, or all of the modes of itsuse, what I claim and desire to secure by Letters Patent is 1.
